So you're claiming that the 757 engine weght is between 37,400 and 40,000? Try thrust rating, not weight my friend. The Trent 900, which is for the
A380 is the largest engine ever made by Rolls Royce, and it weighs in at 6300 kilos, which is roughly 13860 pounds, or just under 7 tons. But the
smaller RB211-535 used on the 757 is going to weigh that much more? I don't think so.
The weight of the Trent 900 engine itself is roughly 6300 kg, with a length of 5.3 metres, a diameter of circa 3 metres and with all externals
roughly four metres in diameter. Each Trent 900 offers take-off thrust of between 330 and 375 kN (74000-84000 pounds), depending on the variant. The
twin-deck 555-seat Airbus A380 will be equipped with four Trent 900 engines, and thus will be able to take off with a thrust of up to 1500 kN, or
336,000 pounds.

The Rolls-Royce Trent 900, the largest aero engine the company has ever built, will be unveiled along with the new Airbus A380 at a special
ceremony in Toulouse on Tuesday (18 January).
With a fan diameter of 116 inches, the Trent 900 is physically the largest engine ever built by Rolls-Royce. It is also the world’s
cleanest large turbofan engine, measured by emissions per pound of thrust.

This is essentially a scaled down version of the -524. Its thrust range spans from 37,000 to 43,100 pounds-force (165 to 192 kN). It powers
Boeing 757 and the Russian Tupolev Tu-204 airliner. It is 180-minute ETOPS rated. The later series shares common features with the later series -524
such as wide-chord fan and FADEC. The 535E-4 was proposed by Boeing for re-engining the B-52H Stratofortress, replacing the aircraft's eight TF33s
with four of the turbofans.

I'm waiting for some information on the dry weight of the engine, but I saw somewhere that it was 3.2 tons. I'd be really impressed if they hung
two 40,000+ pound engines on those wings.
